資金流向方面，數據統計發現，昨日板塊內共有34只概念股呈現大單資金凈流入態勢，其中，世榮兆業(7702.61萬元)、珠海港(5620.46萬元)、廣州港(2875.84萬元)、珠海中富(2101.37萬元)、深深寶A(10.470,0.00,0.00%)(2061.87萬元)、華發股份(2000.39萬元)、白云機場(16.250,0.00,0.00%)(1944.6萬元)、科順股份(14.510,0.00,0.00%)(1859.42萬元)、沙河股份(1809.13萬元)、江龍船艇(28.010,0.00,0.00%)(1784.96萬元)、格力地產(1450.2萬元)、金溢科技(1128.63萬元)和鹽田港(7.850,0.00,0.00%)(1044.57萬元)等13只概念股大單資金凈流入均在1000萬元以上，合計吸金3.34億元。

粵港澳大灣區已上升至國家戰略，粵港澳大灣區規劃出臺在即，成為機構提前布局相關概念股的重要原因。近期，全國政協港澳臺僑委員會主任朱小丹透露了粵港澳大灣區的最新動態，他表示，大灣區發展規劃綱要將出臺，國務院在作最后修改，預計5月上旬正式公布。

除大單資金青睞外，早在一季度社保基金與QFII等兩類機構資金就已對粵港澳大灣區相關概念股進行布局。根據一季報披露顯示，21家粵港澳大灣區相關上市公司前十大流通股股東中出現上述兩大機構身影，合計持股數量6.10億股，合計持股市值約96.50億元。其中，有11只個股成為上述機構集體在今年一季度新進增持的重點，其增持資金達到13.47億元。新進方面，社保基金與QFII兩機構在今年一季度新進持有達實智能(5.190,0.00,0.00%)、中遠海特(4.480,0.00,0.00%)、瑞凌股份(6.180,0.00,0.00%)等3只相關概念股，新進持股數量分別為877.08萬股、730.58萬股和82.20萬股;社保基金與QFII兩機構在今年一季度對招商蛇口(23.170,0.00,0.00%)(3825.39萬股)、瀚藍環境(16.200,0.00,0.00%)(1111.50萬股)、世榮兆業(725.97萬股)、中炬高新(26.220,0.00,0.00%)(469.22萬股)、廣州港(397.41萬股)、粵電力A(4.450,0.00,0.00%)(200.00萬股)、陽光城(7.430,0.00,0.00%)(123.54萬股)和新綸科技(14.290,0.00,0.00%)(83.00萬股)等8只個股進行繼續加倉操作。

更為重要的是，二季度以來截至昨日，盡管A股市場呈現震蕩整理的態勢，但個股表現比較活躍，尤其是社保基金與QFII共同持有的21只粵港澳大灣區概念股表現更加出色。按昨日的收盤價計算，二季度以來上述兩類機構所持有的21只概念股倉位累計浮盈達5.11億元，其中，有13只個股二季度以來社保基金與QFII持有的上市公司股票市值實現增長，而招商蛇口、新綸科技、中炬高新、瀚藍環境、白云機場、世榮兆業、華發股份等7只個股上述兩類機構持股市值增長均超1000萬元。

對于板塊的后市機會，萬和證券表示，基于粵港澳大灣區的戰略地位和綜合實力，整體看好相應的投資機會，主要體現在以下三條投資主線：一是人口匯聚將提升灣區地產價值，利好在區域內擁有豐富資源儲備的房地產企業;二是區域內交通便利、對外具備較強的經濟輻射功能，從而有助于第三產業占比的提升，利好交運、港口以及金融服務業等行業;三是智能制造+科技創新，利好制造業轉型升級和利好區域內相關的創投公司。
